Biomass co-firing (direct, indirect, parallel) was successful in over 150 installations worldwide, with different types and amounts of biomass wastes in different combustion and gasification technologies, configurations and plant sizes. An evaluation of the co-firing technology by developed key indicators (environmental impact, applicability, operational experience, efficiency, economics and biomass share) showed that in-direct co-firing is the best technology followed by direct co-firing in pulverised fluidised (PF), bubbling fluidised bed (BFB), and circulating fluidised bed (CFB) boilers.

The improvement of energy efficiency is one of the main targets of EU energy policy. The target of the Slovenian action plan for energy efficiency is to achieve energy savings of 4261 GWh or 9% of final energy consumption by 2016. The developed indictors of energy efficiency for all sectors have been used to calculate energy savings. In the article an analysis of policy, trends and indicators of energy efficiency on the sectoral and country level has been made. The results of the analysis have shown considerable improvement of energy efficiency in the period from 1998 to 2007.

Sequential extraction protocol was performed to assess mobility and bioavailability of 238U, 234U, 230Th and 226Ra in soils from the uranium waste pile at Žirovski vrh and its surrounding. In non-contaminated locations, about 80 % of all radionuclides were in the residual fraction. Considering activity concentrations, 238U and 234U are the most mobile. Mobility of 226Ra is suppressed by high sulphate concentrations and is similar to mobility of 230Th.

Six soil samples were collected near to a uranium mill tailings waste pile. The samples were processed by two sequential extraction protocols and the U, Th and Ra radionuclide content assayed by alpha spectrometric determination. The analysis revealed that results obtained by the two protocols are not fully comparable as data are mostly protocol- and element- dependent. Nevertheless, general conclusions about potential source of the particular radionuclide, which could be drawn from the specific study carried out, are mostly similar for both protocols.

Simulation of fire and its consequences constitutes a cornerstone of modern fire safety engineering especially when underground car park is chosen as the subject of analysis. Each simulation must be based on a realistic fire scenario, which technically formulates social expectation of safety. Setting the realistic goals and outcomes is a real technical problem that requires realistic and reliable inputs. It is found that fire scenario inputs can be statistical weighted and analyzed.
